To estimate the crossover burst size \(\Delta _c\) , it is instructive to determine the probability
that a randomly selected
node of the network is affected by rewiring. The probability that none of the 4 nearest neighbor
connections is rewired for a fiber is \((1-p)^4\) , while the probability that it does not get connected
to any new fiber can be estimated as \(\exp {\left(-4p\right)}\)  for large \(N\)  [1]}.
Hence, the probability \(p_r\) 
that a node is affected by rewiring can be cast into the form
\( p_r=1-(1-p)^4 e^{-4p}. \)
